Restrictions for BGP Support for Multiple Sourced Paths Per Redistributed Route
The following restriction apply to this feature:
-
Paths that are sourced with 0.0.0.0 as the gateway address will not have multiple paths redistributed into the Border Gateway Protocol (BGP). As a result, every sourced path must have a unique gateway.
-
Suppose that for a prefix in the RIB we have a manually configured static route with a tag and a route without a tag inserted through RRI. In such a scenario, the route selection may be inconsistent, and either the manually configured route or the RRI route may be chosen.
To prevent such an inconsistency, perform one of the following actions:
-
If you are manually configuring static routes to all the peer VPN networks of the router, disable RRI by removing reverse route configuration from the crypto map.
-
Set an identical tag in the crypto map for the route inserted through RRI.
